Description Morten Welinder 2006-03-05 02:48:44 UTC 
Removing 1200 columns from a treeview with 1350 columns is very, very slow.
Think minutes, not seconds or centiseconds.  Building the thing was pretty
fast.

(This arose as a side effect of another bug, see bug 333407.  It is, however,
not that hard to trigger this in real life work.)
Comment 1 Jonathan Blandford 2006-03-05 03:27:59 UTC 
Not too surprising -- Columns are implemented using a GList in the TreeView.  It's primarily a unidirectional widget.  I'm not really planning on fixing this.  However, you might be able to make it go faster by removing the columns from the front.
Comment 2 Morten Welinder 2006-03-06 14:27:18 UTC 
I am having trouble believing that the glist is the main cause.  Then building
the thing should be very slow too.
